DDPU-301 polyurethane grouting abu don ceto da taimako
GABATARWA
DDPU-301 abu ne mai nau'i biyu na hydrophobic polyurethane grouting, wanda aka tsara don ceto da taimako.Kayan yana da ɗan gajeren lokacin amsawa kuma da sauri ya canza daga ruwa zuwa siffar kumfa ta ƙarshe.Wannan abu ba zai iya kawai shigar da ruwa mai hana ruwa ba, amma kuma yana da wani tasiri na ƙarfafawa da ƙarfafawa.An yi amfani da shi sosai a cikin ramukan jirgin karkashin kasa, kiyaye ruwa da wutar lantarki, garejin karkashin kasa, magudanar ruwa da sauran wuraren da ba a iya zubar da ruwa ba.
